Animal models of benign airway stenosis: Advances in construction techniques, evaluation systems, and perspectives

Animal Models and Experimental Medicine, EarlyView.
Currently, the animals commonly used to establish animal models of benign airway stenosis (BAS) include mice, rats, pigs, dogs, rabbits, and ferrets. The establishment methods involve one or a combination of two methods such as mechanical injury, tracheal cautery, cuff overpressure intubation, laser injury, and endoscopic silver nitrate cauterization ...

Combination of Time Series of L-, C-, and X-Band SAR Images for Land Cover and Crop Classification

IEEE Journal of Selected Topics in Applied Earth Observations and Remote Sensing, 2022
The availability of new Earth observation satellites operating radar sensors at different frequencies enables the combination of multiple dimensions of the data (time, frequency, polarimetry, and interferometry) in many applications. Image classification

Hanbury Brown-Twiss interferometry and second-order correlations of inflaton quanta

, 2010
The quantum theory of optical coherence is applied to the scrutiny of the statistical properties of the relic inflaton quanta. After adapting the description of the quantized scalar and tensor modes of the geometry to the analysis of intensity ...

Dispersion Effects in Partial Coherence Interferometry: Implications for Intraocular Ranging

Journal of Biomedical Optics, 1999
In nondispersive media, the minimum distance that can be resolved by partial coherence interferometry (PCI) and optical coherence tomography (OCT) is inversely proportional to the source spectral bandwidth. Dispersion tends to increase the signal width and to degrade the resolution.

Advances in Position‐Momentum Entanglement: A Versatile Tool for Quantum Technologies

Laser &Photonics Reviews, EarlyView.
Position–momentum entanglement constitutes a high‐dimensional continuous‐variable resource in quantum optics. Recent advances in its generation, characterization, and control are reviewed, with emphasis on spontaneous parametric down‐conversion and modern measurement techniques.

Biometry in Silicone Oil Filled Eyes. A Review

Oftalʹmologiâ, 2021
The “gold standard” of modern vitreoretinal surgery is silicone oil tamponade of the vitreous cavity. The lens opacity development is in the list of complications of prolonged silicone oil eye filling (from 2 weeks to 2 years).

Colloquium: Quantum interference of clusters and molecules

, 2012
We review recent progress and future prospects of matter wave interferometry with complex organic molecules and inorganic clusters. Three variants of a near-field interference effect, based on diffraction by material nanostructures, at optical phase ...

What can we learn from three-pion interferometry ? [PDF]

, 1997
We address the question which additional information on the source shape and dynamics can be extracted from three-particle Bose-Einstein correlations. For chaotic sources the true three-particle correlation term is shown to be sensitive to the momentum ...
